I have the Show Crome switch block shown below.

Power to it comes from the starter switch originally powering the headlight. It now trips up to three relay coils. The micro relays are inside the headlight housing. One switch and relay turns the 55w driving lights on/off. One relay is controlled by the high/low beam switch. One switch and relay is for the headlight. Yes, I can switch the headlight off which is handy at times. The lamps are powered by a separate 20 amp fused circuit. The third switch powers a Deer Hornet, a powered deer whistle. There is now less than one amp passing thru that vulnerable starter switch and I no longer have problems with it...
